It provides a dedicated mono channel with selectable low-pass, subsonic, and bass-boost controls for tailoring low-frequency output. Its 1-ohm-stable design makes it suitable for systems wired to a compatible final impedance.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners upgrading a vehicle with an aftermarket subwoofer or integrating bass into a factory or aftermarket audio system. RCA and speaker-level inputs support connection to a range of source units. DC signal-sensing turn-on can simplify installation in compatible systems.\u003c\/p\u003e\u003cp\u003eThe CRA-2000.1 is specified for up to 1 x 2000 watts at 1 ohm, with listed outputs of 1 x 1000 watts at 2 ohms and 1 x 500 watts at 4 ohms. A variable 40-300 Hz low-pass filter helps blend the subwoofer with full-range speakers. The 10-40 Hz subsonic filter gives installers an additional tool for system setup.\u003c\/p\u003e\u003cp\u003eCrunch uses a switch-mode power supply and SPEED-FET MOSFET components in this amplifier. The Class D topology is designed for efficient operation in a compact mobile-audio format. A low-noise preamplifier circuit is included to handle incoming source-unit signal.\u003c\/p\u003e\u003cp\u003eThe included wired bass remote allows convenient adjustment of bass level from the driver’s seat. Nickel-plated brass terminals and screw-down connections support secure power, ground, and speaker wiring. It is a practical choice for a dedicated bass channel when paired with properly matched subwoofers, wiring, and electrical protection.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass D Mono Design:\u003c\/strong\u003e Provides an efficient single channel for a subwoofer system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Ohm Stability:\u003c\/strong\u003e Supports compatible subwoofer wiring down to 1 ohm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts the upper bass cutoff from 40-300 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Filters very low frequencies from 10-40 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Places bass-level adjustment within easy reach.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Supports factory and aftermarket source-unit integration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe CRA-2000.1 uses a heavy aluminum heat sink with Crunch Quick Thermal Dispersion Technology to help manage heat. Its power supply uses switch-mode technology, while nickel-plated brass terminals and screw-down connectors are specified for dependable cable connections. LED power\/protect indication and overload and speaker-short protection circuitry are included.\u003c\/p\u003e\u003cp\u003eUse 4 AWG power and ground cable as specified, and install an external 125A fuse in the power cable within 18 inches of the battery connection. Mount the amplifier securely in a well-ventilated location and do not mount it upside down. Match the final speaker impedance to the amplifier’s 1-ohm minimum rating, then set the level, crossover, subsonic filter, and bass boost conservatively to suit the connected subwoofer system.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45621403451462,"sku":"CRA-2000-1","price":210.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/6186aRKSkpL.jpg?v=1784371544","url":"https:\/\/audiowatt.store\/products\/crunch-cra-2000-1-2000w-class-d-mono-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
